Message-Id: <3bdaf787$1_4@news.bluewin.ch>
Hi there,
ive been working with perl for several months now, and now id like to
put a cgi script on my website, just to test it...
id only like the script to print
Hello there
( ;)) its only to test how the CGI thing between browser and Server works,
right!!! ;))
anyway, my script looks like this
#!/bin/perl
print "Hello there\n";
thats all!!
now, ive put this file into my CGI-bin on the server. how do i call the
script now? how do i make it execute itself?
its an easy question, so i hope to get an answer... thanks in advance,
anyway!
greets, steven

Off-topic (you'd be seeing the same problems no matter
what language you used to write the CGI program), try
comp.infosystems.www.authoring.cgi
to see how to operate within a CGI environment.

Actually it will print to stdout, or in this case, the terminal window
which you cannot see.
To print back to the browser you need to tell it to...
#!/bin/perl
print "Content-type:text/html\n\n";
print "Hello World!<BR>\n";
This assumes of course that perl is at /bin/perl on your system.
Execute it with http://yourdomain.com/cgi-bin/its_name.cgi
Be sure and upload it in ascii
Cheers,
Mark

Hi mark, thanks for replying.
oh sure, prints standart output is the screen, obviously.
Okay, ive tried it, but it still wont work.
in the html file main.htm
ive added the entry
<!--#exec cgi="/htdocs/www/cgi-bin/counter.cgi"-->
on www.kontent.de, my website provider, they told me that the absolute path
is /htdocs/www/cgi-bin/filename
my index.html, main.htm etc are all in the folder www!
my Perl script looks excactely the way you told me to
let it look.. ;))
#/bin/perl
print "Content-type:text/html\n\n";
print "Hello World!<BR>\n";
what could be wrong, what else can i check to
see whats not working properly!!

You've switch gears...
<!--#exec cgi="/htdocs/www/cgi-bin/counter.cgi"--> is not a simple cgi
script to execute. Now your talking server side includes. The html file
this is in needs to be an .shtml file and the server needs to be setup to
allow ssi.
Tackle one problem at a time. Will the Hello World! script run? Then will
the server allow ssi?
Cheers
Mark

Excellent advice. And perhaps even more important, get information on
each part of the problem in the appropriate place.
> Will the Hello World! script run?
That is a perl question, if the script will not run from the command
line you can ask about that in this newsgroup.
> Then will the server allow ssi?
That is not at all related to perl. As several people have already
suggested, you need to ask about that in a server or ssi related
newsgroup.

The entry itself appears to be fine at first glance..
rename your main.html to main.shtml
If it works then you know the server is setup to allow ssi.

yes, ive changed the file to shtml already... it works. that means the
shtml is printed, so my host supports SSI, right??
but the hello there is still not being displayed

After another glance your ssi line needs a space in it I think...
<!--#exec cgi="/htdocs/www/cgi-bin/counter.cgi"-->
needs a space after counter.cgi" so it reads...
<!--#exec cgi="/htdocs/www/cgi-bin/counter.cgi" -->

Have you shifted gears again?
<!--#exec cgi="/htdocs/www/cgi-bin/counter.cgi" -->
Should do what ever counter.cgi is designed to do.
If....
#!/bin/perl
print "Content-type:text/html\n\n";
print "Hello World!<BR>\n";
is saved as "hello.cgi" and
<!--#exec cgi="/htdocs/www/cgi-bin/hello.cgi" -->
is in your main.shtml file the "Hello World!" should print in the browser
in the location where the line above is at.
And maybe any further should be done in email or in
comp.infosystems.www.authoring.cgi so as not to further annoy the die hard
perl mongers...
Cheers,
Mark

Thank you, yes. And the other two reasons that is appropriate are 1) so
that Steven can learn to distinguish which problems relate to which
parts of the technology and 2) so that the issue is discussed where
people who know about it hang out. Perhaps Mark is correct in all he
says and knows everything about cgi authoring but on the off chance that
isn't the case, then Steven is better off going to a newsgroup where
people capabable of improving on or adding to Mark's advice are to be
found.

Okay, as you said im not gonna post anymore...
Thanks already for your help.
Loads of people replied, iin all kinds of groups, but not
All of them were patient enough..
Anyway, I think im near it now.
Before, when I tried to run the script www.dsxs.net/cgi-bin/hello.cgi
It said something about a header problem or so.. now it only prints
The hello world! Thingy. that's already quite good, isn't it?? So its
working!!
But I just don't succeed in putting it on the website!! Its just not there!!
Do you think it might be something wrong with the path??

Subject: multiple tag replacement within a string
Message-Id: <20011027140852.A27818@keyslapper.org>
Hey all. I have a string tag substitution question.
I have a string, defined from a config. This string can have a number
of tags like _DATE_ _SERVER_ etc. I have 8 defined in all. For each
tag, there is an internal variable. If that variable is defined, I
want to replace the tag with that value, or else I want to replace it
with the word 'unavailable'.
So far, I have done the following:
if (defined $not_found)
{
if (defined $date) $not_found =~ s/_DATE_/$date/g;
else $not_found =~ s/_DATE_/unavailable/g;
if (defined $server_admin) $not_found =~ s/_ADMIN_/$server_admin/g;
else $not_found =~ s/_ADMIN_/unavailable/g;
# Etc., . . .
}
Which looks a little cumbersome. Especially when you see al 8 tags
replaced. Any ideas on how to make this more elegant and, hopefully,
more efficient?
TIA & HAND

Use the hash Luke! Instead of variables called $date and $server_admin,
have one hash key called configs with keys for those:
my %configs = (
DATE => $date,
S_ADMIN => $server_admin,
# ... other values
);
my %config_string;
if (defined $not_found) {
for my $key(keys %configs) {
$config_string{$key} = $config{$key} or 'unavailable';
$not_found =~ s/_${key}_/$config_string{$key}/g;
}
}
That should replace all of them at once.

if (-e $myfile) {
print "File $myfile exists\n";
} else {
print "File $myfile does not exist\n";
}
You may also want to check if $myfile is a plain file or directory or
symlink or ....

Why re-invent the wheel? Use the CGI.pm module which comes with every
standard distribution of Perl. Try this:
use CGI qw/:standard/;
my $ID = param ('id'); # should give $ID the value 2
my $Text = param ('text'); # should give $Text the value 'hello'
As a bonus, this works regardless of whether the data was passed via POST
or via GET.
Read more about it by typing 'perldoc CGI' at your command-line prompt, or
by going to <http://www.google.com/> and searching for "CGI.pm tutorial".

she is some angry person who doesn't seem to like this group having a
culture of proper quoting and other netiquette. ignore her. newbies are
welcomed here. but there are some cultural rules that make it easier for
all (including newbies) to participate. she thinks no rules and total
anarchy is better then a set of traditions and netiquette.
look for a regular post on posting guidelines for this group and read
it. also read the FAQ as much as you can before you post a question. in
general if you do some work before you post and be reasonable in what
and how you ask, you will very likely get help. if you demand answers
and don't lift a finger first, you will more likely to be ignored. she
thinks that is wrong but of course she won't help anyone with anything
but some stupid nazi flames. hmm, i wonder who is more fascist.

The construct :
print <<EOF;
EOF
is discussed in the perlop manpage in some detail. What you have within
the subroutine is known as a 'here document' it is an idea borrowed from
the Unix shell - it is essentially a form of multiline quoting where the
'<<EOF' is effectively replaced by everything from the next line upto the
line containing the matching tag 'EOF'. So in this example you will have
a subroutine which prints all of the lines between the print statement and
the EOF (bear in mind that this must always be in the first column).
This construct is not just for print statements but can be used anywhere
an expression can be such as in an assignment or as the argument to a
subroutine so you might equally see things like :
my $foo =<<EO1;
Some stuff
EO1
some_subroutine(<<EO2);
Some more stuff
EO2
You get the picture. The delimiting tokens can be anything that you want
as long as they match, although it is conventional that they are uppercase
so they are easily distinguished from other names in the program.
Hope that helps.

It's a sub that prints a here-doc. You can find an explanation of
here-docs (or "here-documents", in full) in perldata.

Escape your quotes within the print lines. As in...
print "<a href=\"http://www.kernel.org\">www.kernel.org</a>\n";

No, that's perl answer! It's perfectly relevant here. :-)
I might suggest using either here-docs or the qq operator instead of
backwhacking the quotes though:
print qq ( <a href="http://www.kernel.org">www.kernel.org</a>\n );
OR
print <<END_OF_HTML;
<a href="http://www.kernel.org">www.kernel.org</a>
END_OF_HTML

CGI.pm has shortcuts (to differentiate this answer from
here-docs and q() answers).
print a({href => 'http://www.google.com/'}, 'search me!');
What I like about this approach is that it cleanly
separates the way in which perl deals with quoting (as
part of the perl syntax) from the encapsulated generation
of HTML and the way in which /it/ handles quoting.

Subject: study() question
Message-Id: <gUBC7.2102$hX3.153661@typhoon1.gnilink.net>
Hello,
I've been reading the perldoc for the study() function, and it's not telling
me something I want to know. Hopefully somebody here knows. Here's my
question, in perl code.
study($data);
my_function($data);
sub my_function {
my $string = shift(@_);
# Is $string studied?
} # End my_function
Strings are pass by value in these functions, so I wouldn't necessarily
expect that it would be studied, because it's not technically the same string
internally in Perl. (Or is it?) But what about this:
study($data);
my_function(\$data);
sub my_function {
my $ref = shift(@_);
my $string = ${$ref};
# $string is studied here, isn't it?
} # End my_function
